Game Clock is a referee-facilitated game clock that is synced and shared with everyone on their device. Our proximity-based game lists and intuitive design ensure that both referees and fans can navigate effortlessly. A user-friendly interface lets you focus on the game, not the clock. Our app features customizable alerts, whether it’s timeouts, halftime, or stoppage time, notifications ensure you’re always in sync with the action. How does it work? - The referee creates the game on their phone or Apple Watch. They can start and stop time as they see fit. The time is synced and shared with anyone tuned into that match. - Spectators view a proximity-based list of games near them and choose the match they are interested in. Instantly they see the running clock on their device and know how much time is remaining in the game. If the ref stops the clock, the clock on the spectator devices also stops. Users can know the remaining time in a game even if they are unable to attend the game or have to be on another field, or if they need to know when to pick up a player when the game is over. This app is great for many sports, including soccer, football, flag football, ultimate frisbee, lacrosse, field hockey, rugby, footy, basketball, and more.
